IMPROVEMENT IN PICKER-STAFF CHECK POR LOOMS.

TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME: 4

Be it known that we, EZEKI'EL -PIIILLIPS and HENRY C. PHILLIPS, ofBlackstone, of' the county of Worcester, and State of Massachusetts,have made a new and useful Improvement in Looms for Weaving; and dohereby declare the same to be fully described in the followingspecification, and represented in the accom. panying drawings, of whichyl Figure -ldenotes a. frontelevaton of our, invention, as applied to thelay and picker-staves of a loom.

Figure 2 is an end view, and

Figure 3 a transverse section ot' it.

(Figures Land 5 are hereinafter described.)

The purpose of our invention is to prevent, after each throw of thepickerwor itsstaii, any improperd'on ward motion of such picker or itsstal?, such as to prematurely advance the shuttle. Our invention alsoenables the stoppage ofthe picker or its stall' to be graduallyetiected, so'as to prevent injury thereto.

A premature advance of the picker or its stal is likely tocorrespondingly advance the shuttle, from which` advance seriousaccidents are liable' to take lplace, in consequence ofthe shuttle beingprotruded into the shade` of the warps. Again, a gradual stoppage of thepicker isV desirable, to prevent the cap, or a portion thereof, frombeing thrown olf the spindle of the shuttle. I

In carrying ont our invention, we combine with the lay A and its twopicker-staves, a friction-apparatus, of the kind hereinafter explained.'At'or near the middle of the lay A, and below the race-beam a thereof,we arrange, in a bearing, Zw, a. friction-roller or-cylinder, c, andhold the same in place by e. brake-cap or cover, d. This cap we supporton springs e e, which rest on washers ff, that in turnare sustained onand by two screws, g gp'which go through the washers and springs,andscrew p into the lay. Fromthe friction-cylinder-c an arm, L, extendsdownward, and terminates in an eye, which is connected withtwo bentlevers B B, hinged to the lower side of the lay, and arranged at or nearthe external termini of the vibratory movements of the two picker-StevesD D, which play within `the lay,'and extend therefrom in the ordinarymanner. Each of the levers B B, we maire ot' wire, bent `in manner andcovered withleather as represented in the drawings, and we connect themwith the lay by leather loops z'z', fastened thereto. Each of the rods k7c, by which the said levers andthe arm of the friction-cylinder areconjoined, we connect to the.said arm and the lever by leather loops lm.One of such pair of the said 'loops we connect to its rod It', by meansof a clamp-screw, m', and anut, n, the latter going through the loop andan eye formed on the rod, the eye being within the loop, and the lattervhaving a slot, o, made lengthwise in it to receive the shank of theclampfscrew. i i

Figure 4 is afront view,

Figure 5 a longitudinal section, and' Figure 6 a. transverse sectionofthe connection ofthe rod c.

The clamp-screw and nut, with the slot in the loop, enable ltheconnection between the leverB and the -arm of thefriction-cylinder to beeither shortened or lengthened as circumstances may require. VDuring theretreat of each picker-steil', it will be thrown against the longer armof the next adjacent lever, B, the movement of which, occasioned by thestad', will he overcome by the 'resistance of the frictiomapparatus, thestaff being brought to a state of rest without any recoil, such asdtakes place when a spring is employed to overcome the momentum of thestaff'. While cachrpickensta may be moving a lever, B, the other lever Bwill be in` corresponding movement, and will he set, ready for a. blowof the other picker-staff.

By applying the friction-*cylinder-hox cap to the lay, -by means asdescribed, the degree or amount of friction or resistance that may berequired to overcome the momentum of the picker-staff can be readilyobtained. l We claim the friction-apparatus, substantially as described,that'is, as composed of the levers B B, the friction-cylinder and itsbearing and cap, and the connection of such cylinder and levers, asspecified.

We also claim the combination of the friction-apparatus,substantiallyasdescribed, or its equivalent, with the' lay and itspickers, or picker-stoves, the whole being arranged and so asto operateas and for the purpose as explained. i p
